When the mining width reaches to the mining subsidence startingdistance, the mining subsidence will grow slowly.
当开采宽度达到地表移动起动距时，地表下沉缓慢增长；

Various combinations of starting altitude and distance between layers will produce different volumetric effects at specific distances and viewing angles.
图层之间的起始高度和距离的各种组合将在特定的距离和视角上生成不同的体积效果。
